摘要：
We report a study of the infrared, photoinduced absorption in a nominally undoped, lattice-matched InGaAs/InP multi-quantum-well (MQW) structure. A clear photoinduced intersubband absorption band is observed and assigned to the n = 1 to n = 2 transition. Its dependence on the excitation (laser) intensity reveals a defect controlled recombination mechanism.
